20090116791 | COUPLING DEVICE FOR A LIGHT GUIDE - A coupling device includes a first coupling element having a first passage, and an end section connected to the free end of the light guide; as well as a second coupling element with a second passage for holding/fixing an intermediate section following the end section of the light guide. In one implementation, the first coupling element and the second coupling element can be detachably joined in a coupled state, where the first passage and the second passage form a common passage and/or have (or surround) a common longitudinal axis. The first passage can be configured with a funnel-shaped section that, in the coupled state, the first passage faces the second passage and widens toward the second passage. In addition, the first coupling element may be formed from ceramic material at least on its inner surface in the region of the funnel-shaped section. | 05-07-2009 |
20090180738 | ANTI-WIGGLE OPTICAL RECEPTACLE - A casing includes a solid sleeve and a split sleeve in combination to provide a connection between a fiber stub and a ferrule containing an optical fiber. The arrangement prevents wiggle of the ferrule, and also does so without the tight tolerances that would otherwise be required in solid sleeve systems. | 07-16-2009 |
20090196554 | COUPLING DEVICE, AUXILLIARY DEVICE AND ADAPTOR FIXING MEMBER - A coupling device for coupling optical fiber cables facilitates positioning in a circumferential direction for coupling a connector. When a connector fixing member is inserted into an adaptor fixing member, a protruding section of the connector fixing member slides along an end surface of the adaptor fixing member, and is automatically guided to a notched section. | 08-06-2009 |
20090257717 | Fiber optic connector assembly and method for venting gas inside a fiber optic connector sub-assembly - A fiber optic connector assembly and method for venting gas inside in a fiber optic connector sub-assembly. The fiber optic connector assembly includes a connector sub-assembly including a ferrule and a ferrule holder having a passage extending therethrough. A stiffener tube having a tube body disposed about a portion of at least one optical fiber supports insertion of the optical fiber into the ferrule holder passage. The stiffener tube contains at least one opening in its tube body configured to vent gas trapped inside the stiffener tube during assembly. In this manner, the trapped gas does not form a gas pocket in the bonding agent, which could compromise bonding among the optical fiber, stiffener tube, and connector sub-assembly. | 10-15-2009 |
20100027942 | Cable connector assembly - A cable connector assembly includes a fitting having first and second fitting ends and a fitting opening therethrough, wherein the fitting is formed from a conductive material. The cable connector assembly further includes a ferrule having first and second ferrule ends, a ferrule opening therethrough, and one or more teeth disposed axially along the ferrule opening, wherein the ferrule is formed from a conductive material. The first ferrule end is disposed over the second fitting end. The cable connector assembly further includes a tube including an outer nonconductive layer and an inner conductive layer. The tube is disposed between the second fitting end and the first ferrule end and the ferrule is secured around the fitting so that at least one of the one or more teeth pierce the outer nonconductive layer and make contact with the inner conductive layer to create an EMI/RFI shield across the fitting, the ferrule, and the tube. | 02-04-2010 |
20100209052 | FIBER OPTIC CONNECTOR ASSEMBLY AND METHOD FOR VENTING GAS INSIDE A FIBER OPTIC CONNECTOR SUB-ASSEMBLY - A fiber optic connector assembly and method for venting gas inside in a fiber optic connector sub-assembly. The fiber optic connector assembly includes a connector sub-assembly including a ferrule and a ferrule holder having a passage extending therethrough. A stiffener tube having a tube body disposed about a portion of at least one optical fiber supports insertion of the optical fiber into the ferrule holder passage. The stiffener tube contains at least one opening in its tube body configured to vent gas trapped inside the stiffener tube during assembly. In this manner, the trapped gas does not form a gas pocket in the bonding agent, which could compromise bonding among the optical fiber, stiffener tube, and connector sub-assembly. | 08-19-2010 |
20110176777 | Apparatus For Optical Fiber Connection - An apparatus for optical fiber connection is provided, including a shell base and at least an optical fiber coupling tube. The inner shape and the outer shape of the shell base are made according to the different types of optical fiber connection apparatus specifications. The optical fiber coupling tube is fixed to the inside of the shell base. The optical fiber tube includes a hard tube wall along the axis of the tube and at least a deformable tube wall. The deformable tube wall is resilient and can be slightly deformed and restored to original shape. When used for connecting optical fibers, the present invention provides precise positioning and the optical signal loss and pulling torque are all within specifications. | 07-21-2011 |
20140205241 | Cylindrical Optical Ferrule Alignment Apparatus - An alignment sleeve for an optical fiber adapter includes features to bring precision alignment between optical fiber cores. The sleeve includes a tubular inner area to accept first and second ferrule ends of first and second connectors. First and second tabs project from first and second ends of the sleeve. The first and second tabs slide into holes in the ferrule holders or barrels of the first and second connectors, so as to provide rotational alignment of the first and second ferrules, which may be presenting multi-core optical fibers. A mid-portion of the sleeve may include geometrical features to enable a snap fit of the sleeve into a housing of the adapter. More than one tab may be employed at the ends of the sleeve, and the tabs may have defined spacing and/or dimensions to enable security keying, only permitting coupling between connectors possessing matching holes in the ferrule barrels. | 07-24-2014 |
